The general plane frame includes four sub-plane frames 40 comprising two longitudinal beams 41 and at least one horizontal beam 42 fixed between the two horizontal beams 41. If necessary, short reinforcing members can be fixed between two horizontal beams 42.
The both ends of the longitudinal beams 41 are pivot-connected correspondingly to the first middle pivot receptacle at the top end of the first external tube 11 of the first leg 10 and the second upper pivot receptacle at the top end of the second internal tube 23of the second leg 20. The tandem pivot-connection of the first and the second upper pivot receptacles enables the four sub-plane frames 40 to form an organ-type folding.
No.2 Embodiment Example
Please see Figs 4, 5 and 6. The folding bedstead comprises two left-right paralleled rows of legs and the general plane frame.
The legs in each row are of two types: one is the first leg 10, which is un-retractable and is provided with the first lower pivot receptacle at the bottom end and the first upper pivot receptacle at the top end; the other is the second leg 20, which is a three-section retractable one that comprises the second external tube 21, the intermediate tube 22 sliding-connected in the second external tube 21 and the second internal tube 23 sliding-connected in the intermediate tube 22. The second lower pivot receptacle is provided at the bottom end of the second external tube 21, and the second upper pivot receptacle at the top end of the second internal tube 23.
Each row of legs includes three first legs 10 and two second legs 20 and the said three first legs 10 and two second legs 20 are arranged alternatively.
According to the need, the left-right corresponding legs of the two rows of legs are connected with a "cross" folding frame between them, and a horizontal beam 14 is fixed between the first upper pivot receptacles at the top end of the two first legs 10 and another horizontal beam 24 is fixed between the second upper pivot receptacles at the top end of the second internal tubes 23of the two second legs 20. The general plane frame includes four sub-plane frames 40 comprising two longitudinal beams 41 and at least one horizontal beam 42 fixed between the two longitudinal beams 41. If necessary, short reinforcing members can be fixed between two horizontal beams 42. The both ends of the longitudinal beams 41 are pivot-connected correspondingly to the first upper pivot receptacle at the top end of the first leg 10 and the second upper pivot receptacle at the top end of the second internal tube 23 of the second leg 20. The tandem pivot-connection of the first and the second upper pivot receptacles enables the four sub-plane frames 40 to form an organ-type folding.
No.3 Embodiment Example
Please see Fig. 7. This example is a kind of air bed comprising an air mattress 50 and a folding bedstead. The air mattress 50 comprises a mantle and an inflation internal core. The mantle is provided with a closable opening, enabling the client to either put the inflation core in the mantle or to take it outside the mantle according to the need. The folding bedstead is as described in No. 1 Embodiment Example. The said mantle is connected on the first and second pivot receptacle of the bedstead.
No.4 Embodiment Example
Please see Figs. 8 and 9. This example is a kind of sectional air bed comprising two air mattresses 50 and two folding bedsteads. The said air mattress 50 comprises a mantle and an inflation internal core. The mantle is provided with a closable opening, enabling the client to either put the inflation core in the mantle or to take it outside the mantle according to the need. The folding bedstead structure is different from that in No. 1 Embodiment Example in that: a clamp is provided on the pivot receptacle on the side of a folding bedstead and a buckle is provided on the pivot receptacle on the corresponding side of another folding bedstead, and the clamp and the buckle form a detachable buckle structure and a rotatable connection when integrated with each other. The mantles of the two said air mattresses 50 are connected respectively on the two folding bedsteads.
No.5 Embodiment Example
This example is a kind of folding bed comprising four supportive mattresses that are fixed on the sub-plane frames and a folding bedstead that is as described in No. 1 or No. 2 example.
No. 6 Embodiment Example
This example is different from the No. 5 one in that: the said supportive mattresses are the sub-plane frames.
The above ones are only good examples of embodying this utility model and can not be used to limit the embodiment scope of this utility model. That is, any equivalent alterations and decorations based on the scope of the application for a patent for this utility model and the content of its description shall be within the scope covered by this utility model patent.
